//给出字符串中的密码
字符串密码= @1234ABCD//字节数组再该字符串的presentation
。字节[] EN codedPassword =新UTF8Encoding（）GetBytes会（密码）;//需要MD5计算哈希
字节[]哈希=（（的HashAlgorithm）CryptoConfig.CreateFromName（MD5））ComputeHash（EN codedPassword）。//字符串重新presentation（类似于UNIX格式）
字符串连接codeD = BitConverter.ToString（散）
   //没有破折号
   .Replace（ - ，的String.Empty）

I use the following C# code to calculate a MD5 hash from a string. It works well and generates a 32-character hex string like this: 900150983cd24fb0d6963f7d28e17f72

string sSourceData;
byte[] tmpSource;
byte[] tmpHash;
sSourceData = "MySourceData";
//Create a byte array from source data.
tmpSource = ASCIIEncoding.ASCII.GetBytes(sSourceData);
tmpHash = new MD5CryptoServiceProvider().ComputeHash(tmpSource);
// and then convert tmpHash to string...

Is there any way to use code like this to generate a 16-character hex string (or 12-character string)? A 32-character hex string is good but I think it'll be boring for the customer to enter the code!

// given, a password in a string
string password = @"1234abcd";

// byte array representation of that string
byte[] encodedPassword = new UTF8Encoding().GetBytes(password);

// need MD5 to calculate the hash
byte[] hash = ((HashAlgorithm) CryptoConfig.CreateFromName("MD5")).ComputeHash(encodedPassword);

// string representation (similar to UNIX format)
string encoded = BitConverter.ToString(hash)
   // without dashes
   .Replace("-", string.Empty)
   // make lowercase
   .ToLower();

// encoded contains the hash you are wanting
